An adiabatic heat exchanger is to cool ethylene glycol (cp = 2.56 kJ/kg ºC) flowing at a rate of 2 kg/s from 80 to 40 ºC by liquid water that enters at 20 ºC and leaves at 55 ºC. Determine:

(a) the rate of heat transfer between the water and the ethylene glycol and

(b) the rate of entropy generation in the heat exchanger
